Free Grammar MCQs with Answers

61. Choose the correct form: If I ____ known about the test, I would have prepared.

• A. have
• B. had
• C. would have
• D. has

Explanation: The third conditional describes an unreal past and takes if plus past perfect in one clause and would have plus past participle in the other. Writing if I would have known is a common error and is marked wrong. The pattern always keeps would out of the if clause.

62. Choose the correct form: He has been working here ____ ten years.

• A. since
• B. for
• C. from
• D. during

Explanation: For introduces a duration such as ten years, while since introduces a starting point such as 2015. From is used with an explicit end point, as in from Monday to Friday. This pairing is one of the most frequently tested points in the grammar section.

63. Choose the sentence that uses the semicolon correctly.

• A. The lecture was long; but interesting.
• B. The lecture was long; it was nevertheless interesting.
• C. The lecture was long; and the students were tired.
• D. The lecture; was long and interesting.

Explanation: A semicolon joins two complete independent clauses without a coordinating conjunction, which is exactly what the second option does. Placing one before but or and is wrong, since those conjunctions already do the joining and need only a comma. A semicolon never separates a subject from its verb.

64. Choose the correct form: The doctor suggested that he ____ more rest.

• A. takes
• B. take
• C. took
• D. will take

Explanation: Verbs such as suggest, recommend, insist, demand and propose are followed by the subjunctive, which uses the base form of the verb regardless of the subject. So it is that he take rather than that he takes. The same form gives it is essential that she be present.

65. Choose the correct transitional device: The first trial failed. ____, the researchers refined the method and tried again.

• A. Similarly
• B. Undeterred
• C. In contrast
• D. For instance

Explanation: The second sentence describes persistence in the face of the failure just reported, and undeterred captures exactly that relationship. Similarly and in contrast both compare two things rather than continue a narrative, and for instance would introduce an example. The connector must match the logical move being made.

66. Identify the type of clause in bold: I know that he is honest.

• A. noun clause acting as the object of know
• B. adjective clause describing he
• C. adverb clause of reason
• D. independent clause

Explanation: The clause that he is honest answers the question what do I know, so it functions as a noun and is the object of the verb. An adjective clause would describe a noun and an adverb clause would modify the verb by telling how, when or why. Testing what question the clause answers identifies its type reliably.

67. Choose the correct passive form: People say that he is a genius.

• A. He is said to be a genius.
• B. He said to be a genius.
• C. He is saying to be a genius.
• D. That he is a genius is say by people.

Explanation: Reporting verbs such as say, believe, think and know form the passive with the pattern subject plus is said plus infinitive. The alternative is the impersonal it is said that he is a genius. Both are common in formal and journalistic writing.

68. Choose the correct form: Not only did he pass, ____ he topped the class.

• A. and
• B. but also
• C. or
• D. however

Explanation: Not only is always completed by but also, and the pair must join grammatically equal elements. The inversion did he pass follows automatically from beginning the sentence with not only. Substituting and or however breaks the fixed correlative pattern.

69. Which of the following sentences has correct subject verb agreement?

• A. The teacher give the students homework.
• B. The teacher gives the students homework.
• C. The teachers gives the student homework.
• D. The teachers given the student homework.

Explanation: A singular subject takes the verb form ending in s in the present simple, so the teacher gives is correct. The third option pairs a plural subject with that singular verb, which is the reverse error, and the fourth uses a past participle with no auxiliary. The rule is easy to state and easy to slip on, because the s ending marks the plural on nouns but the singular on verbs.

70. The keys were found _______ the drawer where you left them last week.

• A. under
• B. in
• C. on
• D. beside

Explanation: A drawer is an enclosed space, so something inside it takes in, while on would place the keys on its surface and under or beside would place them outside it altogether. Prepositions of place follow the geometry of the object: in for enclosed spaces, on for surfaces, at for points. The relative clause where you left them confirms the keys were inside.
